Christianity, Judaism and Islam all contend there is one God, but their cognizance of God differs to the point of exclusion. To you, "the God of Judaism and God of Christianity are one in the same, the only difference is Jews did not accept God's son Jesus as the Messiah."
Maybe you ned to consult some practicing Jews and ask them how come Judaism considers Christianity a different theology, that is why do they consider Christianity incompatible with being Jewish?
Maybe you can increase your IQ score a bit by reading about Christianity as well. Christian God is triune, one essence, three personas, nothing less. To make a statement such as the one you did tells me that you must be one of those heretic protestant "Christians" who make up a "religion" as they go along, and someone who knows not even the essentials of Christianity.
Your second "pearl" is: "Those who claim the founders of this nation to NOT be christians have trouble reading..."
Reading what? Our founding Fathers were wise men who made sure not to mix religion and politics (theocracy), knowing all too well that religions divide, exclude and in general do contrary to the spirit of the American melting pot. Our Founding Fathers were decent people who were not interested in forcing their Christian faith onto others. The God on coins appeared much after them and on $ bills in 1956! Read your history!
They were also decent enough to know that decent people keep their religion as their private relationship with God, and that the idea of Christian faith is not to drum up your convictions and shove your faith down everyones throats -- but to do everything that will make you a better human being and hope that your miserable soul will be saved. There is no other concern of Christianity then the salvation. The fact that various schismatic and heretic braches of Christianity have used it as a "sword" to enhance thier political standing or to conquer other people is a sad legacy to human nature that has proven itself to have fallen from God.
